A Realtor is a real estate professional who is a member of the National Association of Realtors (NAR). A real estate agent who is also a Realtor has agreed to follow the association’s code of ethics, which includes treating all parties fairly, being truthful and honest, and putting the client’s needs before the agent’s. When marketing his business, a Realtor should utilize the tools and advantages he receives when he becomes a member of the NAR.
